SMS spoof is a PalmOS application that allows you to send spoofed SMS messages.
It uses a dialup connection to an EMI/UCP-compatible SMSC. It can be used with
a modem connected to the Palm, such as an IR link to a GSM phone with a
built-in modem. SMS spoof has been tested with Telenor's SMSC in Norway, but it
should work with any SMSC that supports the EMI/UCP protocol, as long as no
authentication is required.
